In this analysis the structural integrity of the rotational system of a standardized roll-on, roll-off sensor pallet system was authenticated. The driving force behind this analysis was to ensure the structural integrity of the system and to locate the areas with optimization potential. This process will ideally lead to the weight reduction of individual components thereby allowing for the transportation of greater cargo during flight. Scaling down of these excessive areas will also allow for a reduced production cost and an increase in efficiency of the system. The study was comprised of the failure susceptibility of the individual components of the system. The major results include the optimization potential of individual components, as well as strategically rating and categorizing the failure capability of the components.

A detailed analytical study of a wheeled double-articulated skidder is performed. Also experimental verification of the stability analysis is made using a scale model of the vehicle. The double articulation joint allows both halves to rotate vertically as well as hinge horizontally. Equations locating the centers of gravity of each section of the vehicle are developed for the three basic modes of stability. The three basic modes of static stability are front section tipping, rear section tipping and the entire vehicle tipping as a unit. The problem is complicated by including the cable winch load on the rear section of the skidder. This load varies in magnitude and direction. The results are presented as stability curves in terms of hill slope, steering angle, vehicle orientation angle, articulation angle and cable force. The analytical model and experimental model were in agreement.
